Subroutines for LAN Control
E.3 Stopping the NISCA Protocol
Table E–3 SYS$LAVC_STOP_BUS Status
Status Result
Success Indicates that PEDRIVER is attempting to shut down the NISCA protocol on the
specified adapter.
Failure Indicates that PEDRIVER cannot shut down the protocol on the specified LAN
adapter. However, PEDRIVER performs the shutdown asynchronously, and there
could be other reasons why PEDRIVER is unable to complete the shutdown.
When the LAVC$STOP_BUS module executes successfully, the following deviceattention
entry is written to the system error log:
DEVICE ATTENTION . . .
NI-SCS SUB-SYSTEM . . .
FATAL ERROR DETECTED BY DATALINK . . .
In addition, the following hexadecimal values are written to the STATUS field of
the entry:
First longword (00000001)
Second longword (00001201)
This error-log entry indicates expected behavior and can be ignored. However, if
the first longword of the STATUS field contains a value other than hexadecimal
value 00000001, an error has occurred and further investigation may be
necessary.
